How can I pass an ImageView resource from one activity to another activity? Have tried imagview.resource and imageview.drawable to pass this data through intent. But neither works.

![enter image description here][1]

Below, I want to send image 1 to add in recyclerview of image 2.

  • Do you use `db` to load data in RecyclerView? add your model and adapter code to investigate – Md. Asaduzzaman Dec 06 '19 at 11:06
  • Passing the whole image resource is a bad idea. How are you getting the images? Are you getting it from a server or loading from app resources? – Froyo Dec 06 '19 at 13:47

unreachable, but you can get the value you want by making imageview.setTag (key, tag) and then pulling it with the imageview.getTag() function.

Convert drawable to Bitmap and then into byte array form and then you can pass it via intent to another activity

Convert Bitmap to Byte Array:-

Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();

Pass byte array into intent:-

Intent intent = new Intent(this, NextActivity.class);
intent.putExtra("picture", byteArray);
startActivity(intent);

Get Byte Array from Bundle and Convert into Bitmap Image:-

Bundle extras = getIntent().getExtras();
byte[] byteArray = extras.getByteArray("picture");

Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
ImageView image = (ImageView) findViewById(R.id.imageView1);

image.setImageBitmap(bmp);

  • This is not an optimal approach. Intent has a limit of 1MB data. If the bitmap data is more than 1MB, it would crash the app. – Froyo Dec 06 '19 at 13:46
